I recall that somewhere they have stated that the reason we absolutely need to teach sex education to the kiddies is that "Oh, well they are going to do it anyways" and "most of these kids don't get any education on sex at home".
Between Hollywood and Kinsey devotees, I don't know how parents can protect their children any longer from the vulgarity, obscenity and passionate incivility that completely surrounds us.
It’s preparation for college, where the real vulgarity begins. Depravity is considered higher education, and some teachers have one mission in life: to disseminate their sickness to as many young minds as possible. 50 years ago they would never have gotten a license to teach.
